I have to say I worked with an orthopedic surgeon for a year and this is one of the most unique injuries I have seen.

Since you are a geeky ortho in training, it's actually got quite a colorful history.

Lisfranc was a French calvery surgeon during the 1800s. The injury frequently occured during when calvery solider was shot, and subsequently fell from his steed. More often, his foot was entangled in the stirrup causing the same injury. At that time, the injury would gangrene, causing the loss of most of the leg. Lisfranc realised the severity of the injury (and the vascular compromise) and amputated earlier (and at that point of the foot).

BTW, of all the photos I found of the Lisfranc injuries on the interwebs, I think this one might be the most severe. Most of the photos I saw they had to use arrows and circles to show you the fault....
